Which compiler would be required for this (https://github.com/corsix/amx/blob/main/aarch64.h)?

I understand the limitation is not at the OS side, as nothing can be done there, but at the compiler-side (I mean that the Apple-supplied compiler doesn't compile against the AMX instruction set, so you'd need a compatible one that, I understand, doesn't exist).

Or is it just undocumented and you can actually get it to work with a Standard xcode and macOS installation given the headers provided?
